The following computer-generated description may contain errors and does not represent the quality of the book:When I, four years ago, came to a determination to go through all our materia medica, and not, as formerly, exclusively deal with the more important medicines, it became immediately clear to me that our handbooks of materia medica (excepting the Encyclopedia of T. F. Allen) did not embrace the whole list of homœopathic remedies. The excellent handbook of Professor Allen contained the greatest number, while the text-books of Drs. Cowperthwaite and Jessen (the latter also a good book for the wants of practitioners) have been found more serviceable in size for daily employment. I accordingly took the text-book of Cowperthwaite as my basis, and added to this a great number of notes, which the author intends to embody in the new edition. The remedies, that were not found by me in the text-book of Cowperthwaite, I in particular brought together to form a text-book of materia medica and therapeutics of the rare homœopathic medicines. A physician, by means of the text-book of Cowperthwaite and with the help of the present Supplement, will now have the whole homœopathic materia medica at his disposal.
